CAR-AXLE BRASS.

SPECIFICATION formingpart of Letters .Patent No. 652,026, dated June 19,1900.

Application filed December 9, 1899. Serial No. 739 766. (No model.)

To all whom it may concern:

Be it known that I, EUGENE JACQUEMIN, of the city of Minneapolis, countyof Hennepin, State of Minnesota, have invented a certain new andImproved Oar-Axle Brass, of which the following is a specification.

This invention relates to improvements in brasses or bearings forcar-axles; and the invention consists generally in a brass having in itsbearing-face a series of diagonal grooves terminating in pockets thatare larger than the grooves and whereby the lubricating material isevenly distributed over the face or wearing-surface of the bearing, andwhich grooves serve to collect and conduct away any grit that is takenup by the axle, whereby much wear is avoided.

In the accompanying drawings-forming part of this specification, Figure1 is a longitudinal vertical section of a car-axle having my improvedbearing arranged therein. Fig. 2 is a view looking at the under side ofthe bearing or brass,

of Fig. 2.

In the drawings, Fig. 1, 2 represents the journal portion of an ordinarycar-axle, and 3 the usual journal-box. The box is provided, as usual,with a removable bearing or brass 5. The brass 5 in its wearing orjournal face 4: has a series of diagonal grooves 7. These groovespreferably terminate in the pockets 8 in the lower edges of the brass.The lower part of the journal-box is usually stuffed with waste, whichis saturated with oil, and as the axle rotates the oil is carried upwardthereby into the pockets 8 on'one side of the bearing or brass and willbe carried through Fig. 3 is a section on line a: m of Fig. 2. Fig. 4.is a section on line y y the grooves and from thence distributed evenlyupon every part of the bearing-sur face 4, no part being allowed toremain dry. The surplus lubricant will pass out through the other endsof the grooves and any grit that collects upon the axle or in the wasteand is carried into the journal will be carried into and caught by thegrooves, from which the grit will be Washed by the streams of oil, sothat the bearing=surface 4 is saved and cut ting or undue wear isavoided. I prefer that the grooves 7 should be arranged at such an anglethat the ends thereof overlap upon opposite sides of the bearing, thusassuring an even distribution of oil upon the bearing-sur face 4.

The brass is provided with the usual lugs and locking-surfaces to engagethe lugs in the topof the journal-box.

The diagonal grooves may extend only part Way across the bearing; butthe construction shown is preferable.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- A car-axle brass, having the usual holdinglugs orlocking-surfaces, and provided with a series of diagonal grooves in itswearingsurface, said grooves terminating in the larger pockets at theends, as described, and for the purpose specified.

In testimony whereof I have hereunto set my hand, this 5th day ofDecember, 1899, at Minneapolis, Minnesota.

EUGENE JAOQUEMIN.

In presence of-- RICHARD PAUL, 0-. G. HAWLEY.
